Which equation represents a line that is perpen- dicular to 3x + 4y = – 4 and goes through the
point (2, -1)?

Step-by-step explanation:

let L1 amd L2 are perpendicular lines then their

slope product is -1

first write the equation in the form Y=mX+b

L1;3x+4y=-4

y=-4-3x/4

Y=-3/4X-1

slope m1=-3/4

m1*m2=-1

m2=-1/m1=4/3

y-y1=m(x-x1)

y-(-1)=4/3(x-2)

y+1=4/3(x-2)

3y+3=4x-8

3y-4x=-11 is the equation of perpendicular lines.

-4
